Divine D Rev. 1.1: MainPCB Layout Complete.
The layout phase has wrapped and the boards are now in production.
Besides the changes previously mentioned here (https://docs.dawndrums.tn/blog/dd-rev1.1-arch), what's more making it into this revision:
- RK3172 LoRa module
- LG77L as a standalone GNSS receiver
- Three chip antenna for WiFi, Bluetooth and GNSS, with high efficiency
- Mechanical optimizations for a more compact 5.5" design.
More updates once the fab house delivers.
We have finalized the schematics for Divine D. Rev. 1.1 and are now moving to the layout phase. The hardware architecture includes new subsystems such as microSD Express, micro HDMI, LoRa, and an under-voltage battery monitor.
Additionally, a Pogo interface allows for accessory connections, exposing USB 2.0, SPI, JTAG SWD, I2C, terminal UART, GPIOs, and a bi-directional power path. For more details, check our blog: https://docs.dawndrums.tn/blog/dd-rev1.1-arch/
Meet Divine, a GNU/Linux Phone powered by Rockchip’s RK3588S. Divine D. will be our first variant, completely open for development, testing and debugging. It will bring interesting features on-board, from local AI to multi-standard connectivity. We also develop DawnOS, a mobian-based distribution tailored for our hardware, including custom Kernel and device tree.
